Updated title to reflect that it's not just bloonchipper, but all fpmcu-unittests packages.

Status: Won't Fix (Infeasible)

The title says fails to build because std::auto_ptr was removed, but I don't think we're using std::auto_ptr anywhere (at least not intentionally), and I don't see it mentioned in the error message.

For this error,

/usr/bin/../include/c++/v1/__config:821:8: error: "No thread API"
  821 | #      error "No thread API"
      |        ^

We do build libc++ with thread support disabled, since the EC OS does not support threads.
